| 摘 要： | 采用连续玻璃纤维增强聚丙烯(PP)预浸布制备复合材料层压板,通过人工加速老化的方法,对不同铺层的连续玻璃纤维增强PP复合材料进行常温、60℃、80℃的海水浸泡实验,研究连续玻璃纤维增强PP复合材料的弯曲强度随老化时间、老化温度等因素的变化规律及性能退化趋势。研究表明,老化初期吸水趋势符合菲克扩散,老化程度与时间和温度成正比关系。对试样断裂部分拍摄扫描电子显微镜(SEM)图像,观察不同环境条件下样品老化情况,老化温度越高、时间越长,增强纤维与树脂基体界面腐蚀越严重。

| Abstract: | Continuous glass fiber reinforced polypropylene (PP) prepreg is used to fabricate composite laminates.Continuous glass fiber reinforced PP composites are subjected to normal temperature,60 ℃ and 80 ℃ brine immersion experiments by artificial accelerated aging method.The flexural strength and performance degradation of the composite are investigated with aging time,aging temperature and other coefficients.The results show that the trend of moisture absorption was in accordance with Fick's spreads at the beginning of aging,and the degree of aging was proportional to time and temperature.The aging degree of the samples under different environmental conditions were examined by scanning electron microscopy (SEM).With the increase of aging temperature and time,the interface corrosion increases between the reinforcing fiber and the resin matrix. |
